UNITED STATES i GERSON Gr. FREUND, OF NEW' YORK, N.

VACUUM BOTTLE.

Application led August 24, 1923.

To all 107mm t may concern Be it known that I, GERsoN G. FREUND, acitizen of the United States, and a resident of the city, county, andState of New York, have invented a certain new and useful Improvement inVacuum Bottles, of which the following is a specification.

This invention relates to an improvement in vacuum bottles andparticularly to the means for holding the interior doublewalledcontaining chamber properly within the outer casing.

Many of the vacuum bottlesmanufactured at the present time protect thedoublewalled chamber by interposing between it and the outer meta-lcasing a section of corrugated card-board or like material. Suchmaterial is usually of an absorbent nature and soon becomes saturatedwith liquids which pass between the neck of the chamber and its outercasing, making the card-board packing smelly and disagreeable andrendering the bottle unsanitary.

The object of this invention therefore, is to provide a packing orspacing means adapted to be interposed between the outer wall of thecontaining chamber and the inner side of the outer casing, which may bereadily placed in position or removed and which will be sanitary underall conditions of use. i

With these objects, and other objects which may hereinafter appear, Ihave devised the particular arrangement of parts set forth hereinafterand more particularly pointed out in the claims appended hereto.

Reference is to be had to the accompanying drawing, forming a parthereof, in which,

Figure l is a front elevation of the containing chamber, parts beingbroken away to disclose construction, and the outer casing for thechamber being shown in section;

Figure 2 is a fragmentary section of a portion of the bottle, showingthe annular spacing member and the groove formed in the outer wall ofthe bottle and in which the spacing member is held; and

Figure 3 is a sectional view on the line 3-3 of Figure l, looking in thedirection of the arrows.

Throughout the various views of the drawings, similar referencecharacters designate similar parts.

In the preferred embodiment of my invention as' disclosed in theaccompanying draw- Seral No. 659,039.

ing, 1 indicates the double-walledr bottle or l containing chamber,which may be of any particular form and which is in most instances madeof thin glass, and provided with an outer wall 2 and spacedintegrallyformed inner wall 3.

The bottle l is contained within an outer casing, usually of metal, andfor protective purposes spaced therefrom by suitable packing. Incarrying out my invention I make use of a number of resilient annularspacing members 4 which rest in grooves or annularv depressions 5 formedin the outer wall 2 of the bottle by depressing the same inwardly atspaced points as indicated at 6.

As many of these spacing members 4 as may be required can be used. Ihave found it desirable to use a soft resilient and elastic rubber forsaid spacing members and if desired the same may be made of tubularconstruction. They are preferably made of such thickness that theyproject well out beyond the outer face of the bottle and bear withresilient pressure against the inner face of the side wall of the outercasing 7 and act to insulate the bottle from such shocks as the outercasing may be subjected to.

The outer casing 7 vis usually provided with a cap or cover of theconventional form, but as the same is no part of my invention it is notshown.

The bottom or lower end of the bottle l is usually resiliently supportedwithin the casing 7 in some manner, and in the drawing I have shown oneof the well-known forms of support, consisting of a coil spring 8. This,however, forms no part of this in vention.

The annular spacing members are preferably held in their grooves bytheir elasticity, but if desired, the same may be cemented in position.It is found desirable, however to have the same readily removable fromtheir grooves so that the same can be replaceable in case of breakage.

From the foregoing, it is obvious that my invention is not to berestricted to the exact embodiment shown, but is broad enough to coverall structures coming within the scope of the annexed claims.

What I claim is l. An article of the class described comprising a vacuumbottle having a doublewalled receptacle, an outer casing for saidreceptacle, a recess formed in the outer wall of the receptacle, anelastic spacing member lie-ld in said recess and adapted to hold saidreceptacle spaced from its casing.

2. An article of the class described coinprising a vacuum bottle, anouter casing therefor, a plurality of spaced grooves in said bottle andspacing members seated in said grooves and holding the bottle spacedfrom its casing.

3. An article oit' the class described coinprising a double-walledreceptacle having spaced depressions in its outer wall, an outer casingfor said receptacle and resilient spac ing members seated in saiddepressions and adapted to hold the receptacle spaced from its casing.

4. An article of the class described comprising a double-walledreceptacle having an annular groove in its outer wall, an annula-relastic spacing member resting in said groove and extending beyond theouter face of said outer wall, and a casing for the receptacle adaptedto be held away from the sides oi said receptacle by the said spacingmember.

An article of the class described comprising a receptacle having aplurality of annular grooves in its outer face, annular spacing membersheld in said grooves and extendingbeyond the outer iace of said wall,and a casing for the receptacle adapted to be held away from the sidesof said receptacle by said spacing members.

Signed at the city, county and State of New York, this 20th day ofAugust, 1923.
